'Application filed August 26, 1914. Serial No. 858,673.

T all whom it may concern Be it known that I, EDWARD MANGISCH, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements-in Folding Balconies, of which the following is a specification.

This invention relates to folding balconies and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a balcony adapted to be applied to window openings for the purpose of sustaining a person during the operation of cleaning the window. The balcony may also be used for other purposes as for instance as a place for rest or observation and as a support for one performing work at the outer side of a building in the vicinity of the window opening thereof.

With the above objects in view the balconyis so constructed that it may be extended or contracted longitudinally thereby being adapted to fit windows of different sizes. Means is provided for accomplishing the adjustment of the balcony just above described from the inner side of the window while the balcony is upon the sill. The balcony is also adapted to be collapsed or folded when not in use in order that it may occupy but little space when in storage or during transportation.

In the accompanying drawings :-Figure 1 is an end elevation of the balcony showing the same in position in a window opening. Fig. 2 is a top plan view of the balcony with parts broken away and parts removed. Fi 3 is a transverse sectional view of the b5 cony showing in dotted lines the manner in which the same may be collapsed. Fig. 4 is a perspective view of the frame work of the balcony. Fig. 5 is a detailed perspective view of one of the floor sections of the balcony with lazy tong means for moving the same.

The frame of the balcony comprises end rods 1 having at their inner ends downwardly disposed lugs 2 (see Fig. 1) which are adapted to rest against the outer edge of the window sill of the window opening as shown in the said view. Angular braces 3 are connected with the lugs 2 at their inner ends and at their outer ends with the outer portions of the rods 1 and thrust screws 4 are threaded in the said bracket and are adapted to bear against the outer surface of the wall of the building as illustrated in Fig. 1 whereby the arms are held in proper horizontal position with relation to the wmdow opening.

Rods 5 are pivotally connected with the inner ends .of the rods 1 and arms 6 are movably mounted upon the inner ends of the rods 5. \Ving nuts 7 are screw threaded upon the inner end portions of'the rods 5 and are adapted to be used for moving the arms 6 along the said rods 5. Thrust screws 8 are threaded in the free end portions of the arms 6 and are adapted to bear against the inner surface of the wall to which the balcony is applied as best indicated in Figs. 1 and 2 of the drawings. Standards 9 are pivotally mounted at the outer ends of the rods 1 and lazy tong levers 10 are in part supported by the said standards in any suitable inanner whereby the standards may move toward each other or move away from each other. The frame of the balcony also includes an intermediate rod 11 which is hingedly connected at its inner end with a bracket 12 adapted to rest upon the sill of the window opening as best shown in Fig. 3

of the drawings. A rod 13 is pivotally connected with the bracket 12 and an arm 14 is movably mounted upon the rod 13. A wing nut 15 is screw threaded upon the rod 13 and when turned is adapted to move the arm 14 along the rod 13 whereby the bracket 12 may be drawn into close engagement with the outer portion of the window sill and thus the inner portion of the rod 11 is supported. A standard 16 is pivotally mounted at the outer end of the rod 11 and a collar 17 is slidably mounted onthe said standard 16. Links 18 pivotally connect the collar 17 with the standards 9 whereby these standards 9 and 16 are caused to swing upon their pivotal connections with the rods 1 and 11, respectively, at the same time. Bearings 19 are carried at the under side of the rod 11 and a' shaft 20 is journaled in the said bearings. The shaft 20 is externally threaded and engages the internal thread of a sleeve 21 mounted thereon. Links 22 pivotally connect the sleeve 21 with the end rods 1 as best shown in Fig. 4 of the drawings. A beveled pinion 23 is mounted upon the inner end of the shaft 20 and meshes with a pinion 24 journaled upon the rod 11. A crank handle 25 is fixed to the pinion 23 and by rotating the crank handle 25 the pinions 24 and 23 cause the shaft 20 to rotate in the bearings 19 ,end to the sleeve 21 and is then trained around the pulley 27-a'nd then under the pulley 26 and attached at its other end to the collar 17. A pulley 29 is journaled at the upper outer. end of the standard 16 and a pulley 30 is journaled at the outermost bearing 19. A cable 31 is attached at one end to the collar 17 and is then trained over the pulley 29 then under the pulley 30 and is connected at itsother end with the sleeve 21. Therefore when the sleeve 21 is moved along the shaft 20 the cables 28 and 31 are moved longitudinally, whereby the collar 17 is moved toward the point of pivotal connection between the standard 16 and the rod 11 when the sleeve 21 moves toward the outer end of the rod 11. and Vice versa. By this movement the links 18 and 22 are caused to swing and assume the positions shown in dotted lines is Fig. 4 and the rods 1 are brought toward each other. A pulley 32 is journaled at the side of the outermost bearing 19 and a cable 33 is attached to the lower,

end of the standard 16-and is passed under thepullev 32 and is attached to the sleeve 21. Consequently when the sleeve 21 moves toward the outermost bearing .19 the standard 16 may swing down toward the innermost end of the rod 17. When the standard 16 swings down as above indicated the standards 9 also swing down by reason of the fact that they are connected with the sleeve 17 through the links 18. Therefore at the time that the rods 1 are brought toward each other and assume the dotted positions as shown in Fig. 4 the standards 9 and 16 swing in a downward direction as indicated by the dotted lines in Fig. 3 and thus the parts of the frame of the balcony are col lapsed or folded.

Lazy tong levers 34 are operatively connected. with the standards 1 as best indicated at the upper portion of Fig. 2 and these lazy tong levers are provided at their points of intersection with eyes 35 which are pivotally connected with lugs 36 carried by floor sections 37. These sections overlap each other and consequently are adapted to fold one upon the other when the lazy tong levers 34 are swung. Standards 38 are mounted upon the outermost floor section 37 and collapsible gates 39 are pivotally mounted upon the said standards. The gates 39 are provided at their free edges with rings 40 which are adapted to engage over the upper portions of the standards ,9 when the balcony is in extended position. Therefore it will be seen that the-area of the floor of which the sections 37 are components increases or diminishes as the rods 1. are moved toward or away from each other. The floor sections 37 are provided at their outer ends with upstanding flanges 41 which are adapted to overlap each other as the sections 37 overlap each other. Lazy tong levers 42 are operatively connected with the standards 9 and are adapted to expand or fold as the said standards are moved toward or away from each other as hereinbefore described. 7

From the above description taken in conjunction with the accompanying drawing it will be seen that a folding balcony structure is provided which may be adjusted to fit window openings of different sizes and that the parts may be easily and conven iently operated to place the balcony in po sition and to remove the same from a window opening.

Having described the invention what is claimed is 1. A folding balcony comprising a frame consisting of end members, means for securing said members to a window opening, said frame also including an intermediate member, means for securing said intermediate member to the window opening, stand ards pivotally mountedat the outer ends of all of said members, a collapsible wall member carried by said standards, an extensible floor structure carried by the rods,fcollapsible end walls or gates located at the outermost floor sections, means mounted upon the innermost rod for drawing-the outermost rods toward the innermost rod and for spreading the outermost rod from the innermost rod, means connected with the said rod moving means for moving the standards s1- multaneously with the rods, said rod drawing means being operatively connected with the intermediate standard to swing the same vertically during the lateral movement of the rods and standards.
